Prices to pay

"Fertilizer prices seem to be one of those areas where the cost increases are most noticeable," Erickson says. "Even though fertilizer prices are up compared to last summer, if you look at them relative to grain prices they're not terribly out of line."

Farmers can expect to pay $151/acre to fertilize their rotation corn crop on average land this year. That total represents a $17 increase since the October estimate. Fertilization costs are projected to rise another $7/acre for rotation soybeans on average land, to $69, compared with earlier estimates.

"For a crop like corn that is more energy intensive, we use a lot more fertilizer," Erickson says.

Propane prices have moderated, leading the Purdue specialists to shift their dryer fuel cost projections downward from October. They expect farmers to pay $26/acre to dry their rotation corn crop from average land, compared with the original $33 estimate.

Crop insurance premiums will be set for the year in early March. Dobbins believes they'll go up.

"The premiums one pays on crop insurance get determined, in part, by what the average price is for corn and beans in February," he says. "The exact cost isn't going to be known for a couple of weeks yet, but it's pretty obvious, I think, that the average price for this February is going to be higher than it was last February, which means crop insurance is going to cost significantly more this year than it did last year."

Since the October crop cost guide was issued, per-bushel prices are up 74¢ for corn, $1.52 for soybeans and $1.21 for wheat. That kind of upward movement in prices indicates farmers shouldn't sell crop insurance short, Dobbins says.

"We're in an environment where that's not a place to think about saving costs this year," he said. "It's an issue of finding the policy that you think will work best for you and pay the premium."

Other management implications from the updated crop cost guide include:

Rotation corn and soybeans or corn, soybeans and wheat provide similar returns on lower-yielding land.

Down the road, the updated crop production estimates are likely to influence the rates farmland owners charge producers to rent their land, Dobbins says.

"Landlords can make these calculations on potential returns as easy as tenants can, and many of them see big numbers at the bottom of these calculations," he says. "So in many areas cash rents are moving up significantly, and so that's going to be an area that people are likely to see a significant rise in costs, as well."
